Union Pacific #70. I believe the model number is 4245 but not sure. It is the singe motor one for what it's worth. Includes original box. It is missing 2 small pieces of hand rail on the back and the "Dependable Transportation" on the "driver (from a automotive perspective) is smudged it looks like. I will get some pics up. I don't know what it's worth, so please make me an offer. I bought it cause it was just a darn neat looking piece! As you can see, I am terrible with a camera.
